Precautionary Guidelines for mobile users
Mobile users are advised to take precautionary measures while using a
mobile handset as:
1. Keep distance – Hold the cell phone away from body to the extent
possible.
2. Use a headset (wired or Bluetooth) to keep the handset away from
your head.
3. Do not press the phone handset against your head. Radio
Frequency (RF) energy is inversely proportional to the square of the
distance from the source -- being very close increases energy
absorption much more.
4. Limit the length of mobile calls.
5. Use text as compared to voice wherever possible.
6. Put the cell phone on speaker mode.
7. If the radio signal is weak, a mobile phone will increase its
20
transmission power. Find a strong signal and avoid movement – Use
your phone where reception is good.
8. Metal & water are good conductors of radio waves so avoid using a
mobile phone while wearing metal-framed glasses or having wet
hair.
9. Let the call connect before putting the handset on your ear or start
speaking and listening – A mobile phone first makes the
communication at higher power and then reduces power to an
adequate level. More power is radiated during call connecting time.
10. If you have a choice, use a landline (wired) phone, not a mobile
phone.
11. When your phone is ON, don't carry it in chest/breast or pants
pocket. When a mobile phone is ON, it automatically transmits at
high power every one or two minutes to check (poll) the network.
12. Reduce mobile phone use by children as a younger person will likely
have a longer lifetime exposure to radiation from cell phones.
13. People having active medical implants should preferably keep the
cell phone at least 15 cm away from the implant.
